Physics Course/FM Modulation

Frequency Modulation - FM
In FM Modulation sound wave is mixed with high frequency carrier wave to generate a wave of three frequencies fs - fc, fc and fs + fc. In general, FM wave is not easy to be interfere with other sound waves in the medium travel through therefore the quality of sound is very good. FM sound wave can travel very far. FM wave is usually use to transmit sound through a long distance. FM wave is usually use to transmit sound globally or internationally
